My phone has run really slow and laggy since forcing the 2.2 update. My task killer had never shown any less then 70M available, and now runs at about a steady 35M. It is painfully slow and murders the battery. I used to easily get two days use without a charge, now I need to charge it before I even go to bed. Someone should be my hero and post a guide how to get back to 2.1 I still have the update.zip for 2.1 if that is all I need let me know!

Well mine certainly isn't any faster, it quite drastically slowed my phone down, no number of reboots has helped at all and I only have 4 apps installed. Though it shows about every single app the phone came installed with running no matter how many times I kill them, and have never opened one, they just constantly run. Most of the features that 2.2 came with are useless to me anyway. Think I will just pull the trigger and finally root it tonight. Or throw the f***ing thing out the window..whichever comes first.

O' that might be the problem, some task killers are not ready for Froyo check with the dev/try and disable it.

and I'm sure you've heard this before, but they conceptually make zero sense on an Android phone and they can actually hurt your performance even when working correctly, if they are set to auto kill. Since, the apps "running" in the background aren't actually using CPU cycles or battery, but pulling them out of memory "killing" them does. You can actually waste system resources killing things that aren't using any resources.

in general everyone should check the compatibility of their apps with Froyo if people are having problems

I actually read something very similar to that right after my last post and have since removed the task killer. Cant say I have noticed any difference other then a blank spot on the home screen so far. But if a factory reset doesn't do anyting when I get home later I am gonna root it and push it up to 1Ghz and see if its not snappy again after that. I hope the reset at least fixes the battery issue which most people seem to report did.
